Title: One way clutch
Inventor: HARRISON ANTHONY WILLIAM
IPC: F16D65/54
Filed: 1960-09-10
Abstract: 983,293. Ratchet clutches; adjusting disc brakes. GIRLING Ltd. Sept. 25, 1961 [Sept. 10, 1960], No. 31257/60. Headings F2C and F2E. A one-way clutch, applicable to an automatic wear-adjuster for brakes, comprises a series of teeth 21 integral with one of the clutch members and formed with short circumferential lands 22 frictionally engaging the edge of a circular opening in the other member. The teeth taper inwardly, the roots being relatively narrow to provide resilience, and their flanks are inclined at a small angle to radial lines passing through their roots. The tooth arrangement may be reversed, the teeth projecting inwardly from one clutch member to engage the outer periphery of a disc portion of the other. The clutch is shown applied to a disc brake in which a pad 10 is engaged with a disc 13 by a cam 14 carried on a pin 15 passing through the side plates 16 of an actuating lever. The wearadjusting mechanism consists of a pair of oneway clutch members 18, 19 mounted on the pin 15 within openings in outer and inner side plate members 28, 23, the plate 28 having a projection 33 normally spaced by the desired clearance from a fixed abutment 11. In addition, the plate 28 has a radial abutment 29 engaging the lower surface of a pin 26 projecting from the operating lever, while the plate 23 has a radial slot 25 engaging the pin 26 and a spring finger portion 31 engaging the upper surface of pin 26. In the event of excessive wear projection 33 engages abutment 11 upon brake application, the clutches allowing the plates 23, 28 to rotate clockwise about mounting pin 5 with consequent distortion of finger 31. Upon release of the brake the finger 31 returns to its normal shape and rotates cam 14 anti-clockwise to compensate for wear. A number of brake applications may be required to obtain the desired clearance between projection 33 and abutment 11.

Title: Improvements in and relating to electromagnetic position indicating devices
Inventor: BAINES ANTHONY PETER
IPC: B66B1/40
Filed: 1954-10-29
Abstract: 826,001. Electric tests. ENGLISH ELECTRIC CO. Ltd. Jan. 27, 1956 [Oct. 29, 1954], No. 31319/54. Class 37. A device for detecting the position of a body, e.g. a cage in a mine shaft, consists of two portions, one comprising a pair of coils for producing anti-phase alternating magnetic fluxes, spaced apart in the direction of movement of the body and a search coil for producing an output E.M.F. dependent on the flux linked with it, and the other a conducting metal member cooperating with the flux-producing coils to vary. the flux linking with the search coil, the arrangement being that the linkage is varied in accordance with the relative position of the two portions. As shown (Fig. 2), the three similar laminated ferro-magnetic cores 30, 31, 32 have enlarged polepieces and are mounted vertically above one another in a position mine shaft near a cage landing position. The top and bottom cores are provided with coils which are excited in anti-phase while the central core is provided with a search coil 37. Attached to the cage is a laminated magnetic core 38 surrounded by a short-circuited single-turn coil 39. The arrangement is that the E.M.F. in the central coil is zero when the coil is symmetrically arranged with regard to the outer armatures. In the arrangement of Fig. 3 (not shown), the magnetizing cores are elongated and have search coils wound on their face. The search coils are interconnected while the cage carries a rectangular copper bar. When the bar enters one pair of polepieces the eddy currents induced in it oppose the energizing flux and lead to increased energizing current which thus increases the flux between the other pair of polepieces. The voltage induced in the coils mounted on these polepieces is thus increased and results in a net output voltage which is zero when the bar is positioned symmetrically with regard to the two pairs of polepieces. In the construction of Fig. 4 the cage carries a laminated ferromagnetic bar 59 while the search coils 58 are mounted on the arms of the ferro-magnetic yokes. The polepieces 54, 55 are elongated. In Fig. 5 (not shown) the polepieces are shorter but the laminated ferro-magnetic bar is elongated.

Title: Improvements in or relating to the automatic frequency regulation of alternating current supplies
IPC: H02P9/42
Filed: 1936-04-14
Abstract: 478,561. Automatic control systems; supply systems. GENERAL ELECTRIC CO., Ltd., and GIBSON, J. W. April 14, 1936, No. 31423. [Class 38 (iv)] Speed.-Frequency regulating means for a group of parallel-connected generators comprises a relay common to all, responsive to integrated frequency error of the group and adapted to control the speed of each, in combination with means responsive to the individual generator loads which modifies the action of the relay upon each generator so that a given load distribution is maintained. The relay comprises a drum switch with speed raising, speed lowering, and lock out segments co-operating with fingers on a common mounting, contact being made with appropriate segments when the integrated frequency error as determined by master or standard timing contacts becomes sufficient. As shown in Fig. 1, a motor 25 synchronous with the group frequency drives the drum segments, which are arranged in sets 21, 22, 23, one for each machine and current is periodically supplied to all the segments by timing contacts 19 controlled by a master clock. When the frequency error is excessive raise or lower relays 9, 11 of each machine will adjust the governor settings by means of motors 1 to correct the frequency error. The governor setting of each machine is also determined by the load thereon and to maintain the load distribution the contact mounting of each machine is according to the governor setting by interconnected torque motors 35, 38 coupled to the governor and contact mounting respectively. In a modification, Fig. 2, load sharing is effected according to Specification 360,593 through the current coils 41 of wattmeter relays which are respectively connected across the secondaries of current transformers energized by the load of the several machines. The frequency regulation is effected by a drum switch 52 which controls a contact 66 to unbalance a Wheatstone bridge determining the energization of additional coils 46 on all the wattmeter relays to adjust pilot motors determining the power input to the several machines. A contact 65 is coupled to the contact mounting 60 on the drum switch, and both are coupled by cascaded torque motors to move according to the combined adjustments effected by the pilot motors. By this means the bridge is rebalanced when the frequency adjustment is terminated.

Title: Production of the antibiotic tetracycline by fermentation
IPC: C07C233/00
Filed: 1954-11-02
Abstract: Tetracycline is produced by cultivating Streptomyces species ATCC 11652, 11653 and 11654, or a mutant thereof, in an aqueous nutrient medium under submerged aerobic conditions.  The medium contains a source of (a) carbohydrate, e.g. molasses, glucose, starch or glycerol, (b) nitrogen, e.g. soyabean meal, wheat gluten, peanut meal, hydrolysate of casein and proteins, (c) growth stimulants, e.g. corn steep liquor, distillers solubles and yeast extract, (d) mineral salts, e.g. sodium chloride, sodium nitrate, potassium phosphate and magnesium sulphate, (e) buffer, e.g. calcium carbonate and antifoaming agent.  Cultivation is at 25-30 DEG  C. and preferably 28 DEG  C. for 2 to 6 days.  The crude broth may be freeze dried before or after filtration of the mycelium to produce a product used as an animal feed supplement or plant growth stimulant.  Tetracycline is recovered by (a) adsorption, (b) precipitation by means of an organic base, an aryl azo sulphonic acid dye or a complex with a polyvalent metal of Group II, (c) solvent extraction.  Adsorption is by means of activated carbon, active earths or ion exchange resins especially sulphonic acid resins at pH 3 to 8.  Solvent extraction is at pH 1 to 2.5 or 7.5 to 10 using a water-immiscible organic solvent such as butanols, pentanols, benzyl alcohol, phenylethylalcohol, glycol ethers, e.g. 2-phenoxyethanol, ketones, e.g. methyl isobutyl ketone, esters such as amyl acetate, propyl acetate and ethyl propionate. The extraction is preferably carried out in the presence of a sequestering agent for polyvalent ions, e.g. polyphosphates, various hydroxy acids such as gluconic acid, citric acid and tartaric acid and amino acids such as ethylene diamine tetraacetic acid.  For precipitation as a metal ion complex, one or more of the metal ions in the form of a watersoluble salt is added to the clarified broth and the pH is adjusted to 7.5 to 9 to precipitate the complex. Metals specified are barium, calcium, magnesium, strontium, beryllium, mercury and cadmium.  A non-toxic complex, e.g. calcium and magnesium can be used per se.  Generally, the metals are precipitated from a solution of the complex and the antibiotic recovered from the residual solution.  For precipitation with an organic base, the base is added to the clarified broth and the pH adjusted to 8-9.5.  Preferably a sequestering agent is present. Specified bases are C8 to C18 alkyl trimethyl ammonium halides, C8 to C18 alkyl dimethyl benzyl ammonium halides, alkyl substituted imidazolines and alkyl amines.  The precipitate is dissolved in a solvent, e.g. methanol and the antibiotic recovered by addition of a mineral acid.  In the case of the dye complex, the dye is added to the acidified clarified broth.  Further purification of the antibiotic obtained by any of the above recovery processes is by dissolving the antibiotic in acidified water and extracting with a water immiscible solvent, e.g. butanol.  Specification 749,779, [Group V], is referred to.

Title: Improvements in or relating to supported nickel catalysts
IPC: B01J23/755
Filed: 1956-10-18
Abstract: A catalyst suitable for hydrocarbon conversion reactions comprises nickel or a nickel compound supported on a refractory oxide, silico-aluminate, or activated clay, the support being in pellet or nodule form and the porosity of the support being lower than the initial porosity thereof, Support materials referred to are silica, alumina, magnesia, chromium oxide, silimanite, cyanite, and kaolin. The porosity of the support may be reduced by removal of a more porous constituent, by addition of a non-porous material, by compression, or by heat treatment. Magnesia nodules are treated with steam under pressure in order to disintegrate nodules containing lime; after washing with water, only nodules poor in lime remain. Calcined sillimanite and cyanite may be similarly treated or may be compressed at high pressure or mixed with kaolinic clay; catalysts prepared from these supports may be arranged in two layers, that first traversed by the gaseous reactants having a lower porosity and a lower nickel content than the other layer.  In examples: (1) magnesite is calcined at 1300-1400 DEG  C., nodules are separated, treated with steam, dried, and impregnated with a nickel salt solution; (2) extruded cylinders of kaolin are heated at 900 DEG  C. or 1100 DEG  C. to reduce their porosity, and then impregnated with nickel nitrate solution.  The catalysts may be used in cyclic hydrocarbon conversion processes, for example the reaction of hydrocarbons with steam and subsequent combustion of carbon deposits on the catalyst as described in Specification 772,787.

Title: Process for the production of soot-carbon, retort graphite, and other carbon products from natural gas
IPC: C01B31/00
Filed: 1919-12-24
Abstract: 137,065. R³tgerswerke Akt. - Ges. June 12, 1918, [Convention date]. Carbon. - Relates to the production of soot, graphite and other carbon products by decomposing natural gas in retorts. The natural gas is supplied continuously to the retorts, and the process is arranged so that only about 65 per cent of the natural gas is decomposed, conveniently by adjusting the velocity of the gas; and the waste gases from the decomposition are employed for heating the retorts, thereby constituting the only combustible required in the process. Thus, the natural gas is supplied through lateral connexions g to the upper parts of vertical retorts b of carbon, " silit," &c., and enclosed in a combustion chamber a. The waste gases escape through passages c, and are conveyed either directly or intermediately through a gas reservoir, to the nozzles d opening into the combustion chamber a, and air for combustion is led to the combustion chamber through nozzles i. From the combustion chamber the waste heating gases are conveyed through a flue f to a recuperator e for preheating the air used for combustion, and in order to accelerate the decomposition, the natural gas.
